Crazy out there theory

I know this is probably gonna get flamed or whatever, but what if Gamefreak decides to add some new pokemon to this game. They can make add about thirty new pokemon to it. I know people want gen VI to be on the 3DS but since Gamefreak is breaking tradition why not add new pokemon. And to make sure that you can still trade between the first Black/White games they can bring back the time machine like they did in gold and silver.Or they can take the boring road and just have pokemon from past generations available before the elite four.
